The 'Firework' singer uploaded a picture of herself hanging out with one of her 'Teenage Dream' co-writers.

Katy Perry has posted a picture on Twitter of her and regular collaborator Bonnie Leigh McKee wearing identical leather jackets.

The 'One That Got Away' singer uploaded the picture earlier today (8^th February) which sees her sporting a studded black leather coat along with recently dyed blue hair.

Katy worked with American singer Bonnie McKee while writing her second studio album 'Teenage Dream', and Bonnie co-wrote Katy's singles 'California Gurls', 'Last Friday Night (T.G.I.F.)' and 'Teenage Dream'.

"Teenage twins at it again…" Katy tweeted this morning.

Earlier this week it was reported that Katy and her husband Russell Brand are hoping to finalise their divorce proceedings by June this year, following their separation at the end of 2011.

The 'E.T.' singer took to the stage for a special Super Bowl pre-game show of 'Teenage Dream' on Sunday (5^th), her first live performance on US soil since news of the divorce broke.

Katy Perry is also due to perform alongside the likes of Adele, Rihanna, Coldplay, Nicki Minaj and Bruno Mars at this weekend's Grammy Awards 2012 (12^th February).
